Kevin Federline is “worried” about Britney Spears and feels that the psychiatric hospital is the best place for her right now, a source tells.He “doesn’t want her to get out until she’s made progress,” the source close to Federline says. “This is obviously going to help her in the end – later, much later.” The source adds: “He’s worried. … He doesn’t even know what’s going to happen next.”

Federline, 29, was not directly involved in the latest events, “but he was aware of what was happening,” says another source, a friend of Federline’s.

“Kevin legitimately wants Britney to get better. He wants her to be in their sons’ lives. He wants them to have a loving relationship. He wants her to get healthy so she can be the mother they need and deserve,” says the friend.

A third source close to Federline says that getting medical help again for Spears,”has been planned for a long time. Her family is behind this.”
